ADCP current measurements (75 kHz) during RV Maria S. Merian cruise MSM97/2

Robert Kopte & Marius Becker
Upper-ocean velocities along the cruise track of Maria S. Merian cruise MSM97/2 were continuously collected by a vessel-mounted Teledyne RD Instruments 75 kHz Ocean Surveyor ADCP. The transducer was located at 6.5 m below the water line. The instrument was operated in narrowband mode with 8 m bins and a blanking distance of 8 m, while 100 bins were recorded using a pulse of 1.42 s. The ship's velocity was calculated from position fixes obtained...

Continuous thermosalinograph oceanography along RV MARIA S. MERIAN cruise MSM98/2

Jens Schneider von Deimling & Michael Schlundt
Underway temperature and salinity data was collected along the cruise track with two autonomous measurement systems. Usually, the systems are changed after 6 hours. While temperature is taken at the water inlet in about 6.5 m depth, salinity is estimated within the interior measurement container from conductivity and interior temperature. Salinity was calibrated independently for both measurement containers (MCs). No correction was done for temperature. For details to all processing steps see Data Processing Report.

Bird migration in space and time: chain migration by Eurasian curlew (Numenius arquata arquata) along the East Atlantic Flyway

Rebecca Pederson, Pierrick Bocher, Stefan Garthe, Jérôme Fort, Moritz Mercker, Verena Auernhammer, Martin Boschert, Philippe Delaporte, Jaanus Elts, Wolfgang Fiedler, Michał Korniluk, Dominik Krupiński, Riho Marja, Pierre Rousseau, Lukas Thiess & Philipp Schwemmer
Migration patterns in birds vary in space and time. Spatial patterns include chain, leap frog, and telescopic migration. Temporal patterns such as migration duration, number and duration of stopovers may vary according to breeding latitude, sex and season. This study aimed to verify these patterns in a long-distance migrant, the Eurasian curlew (Numenius arquata arquata), and to provide a synopsis of spatio-temporal migration patterns in this species of concern throughout the East Atlantic Flyway. We...

Hasselquist, Thierry Helminger, Frida Kaiskog, Emma Karlsson, Torsten Kirchner, Carola Knudsen, Nikola Lenzewski, Sigrid Lindmo, Per Milberg, Daniel Pruchniewicz, Elisabeth Richter, Tobias M. Sandner, Judith M. Sarneel, Ralf Schmiede, Simone Schneider, Kathrin Schwarz, Åsa Tjäder … & Rolf Lutz Eckstein
Plant phenology, i. e. the timing of life cycle events, is related to individual fitness and species distribution ranges. Among the environmental factors, phenology is mostly driven by temperature and day length. Rapid adaptation of their phenology may also be important for the success of invasive plant species. Our main aim was to understand how the performance, timing, and temperature dependence of the phenology of the invasive legume Lupinus polyphyllus varies with latitude. L. polyphyllus...

Data from: Quantifying realized inbreeding in wild and captive animal populations

Ulrich Knief, Georg Hemmrich-Stanisak, Michael Wittig, Andre Franke, Simon C. Griffith, Bart Kempenaers & Wolfgang Forstmeier
Most molecular measures of inbreeding do not measure inbreeding at the scale that is most relevant for understanding inbreeding depression—namely the proportion of the genome that is identical-by-descent (IBD). The inbreeding coefficient FPed obtained from pedigrees is a valuable estimator of IBD, but pedigrees are not always available, and cannot capture inbreeding loops that reach back in time further than the pedigree. We here propose a molecular approach to quantify the realized proportion of the...

Data from: Experimental evolution of external immune defenses in the red flour beetle

Gerrit Joop, Olivia Roth, Paul Schmid-Hempel & Joachim Kurtz
The red flour beetle, Tribolium castaneum, secretes quinones that control the microbial flora in the surrounding environment. These secretions act as an external immune defence that provides protection against pathogens. At high concentrations, however, these secretions are harmful to the host itself, and selection may thus have optimized the level of expression under natural conditions. Here, we show that the expression of external immunity responded to selection during experimental evolution within a few generations. At...

Data from: Diet of the insectivorous bat Pipistrellus nathusii during autumn migration and summer residence

Frauke Krüger, Elizabeth L. Clare, William O. C. Symondson, Oskars Keišs & Gunārs Pētersons
Migration is widespread among vertebrates. Yet bat migration has received little attention and only in the recent decades knowledge of it has been gained. Migration can cause significant changes in behaviour and physiology, due to increasing energy demands and aerodynamic constraints. Dietary shifts, for examples, have been shown to occur in birds before onset of migration. For bats it is not known if a change in diet occurs during migration, although especially breeding season related...

Data from: The dominant detritus-feeding invertebrate in arctic peat soils derives its essential amino acids from gut symbionts

Thomas Larsen, Marc Ventura, Kristine Maraldo, Xavier Triadó-Margarit, Emilio O. Casamayor, Yiming V. Wang, Nils Andersen & Diane M. O'Brien
Supplementation of nutrients by symbionts enables consumers to thrive on resources that might otherwise be insufficient to meet nutritional demands. Such nutritional subsidies by intracellular symbionts has been well studied; however, supplementation of de novo synthesized nutrients to hosts by extracellular gut symbionts is poorly documented, especially for generalists with relatively undifferentiated intestinal tracts. Although gut symbionts facilitate degradation of resources that would otherwise remain inaccessible to the host, such digestive actions alone cannot make...

Data from: The glue produced by Drosophila melanogaster for pupa adhesion is universal

Virginie Courtier-Orgogozo, Flora Borne, Alexander Kovalev & Stanislav Gorb
Insects produce a variety of adhesives for diverse functions such as locomotion, mating, egg or pupal anchorage to substrates. Although they are important for the biology of organisms and potentially represent a great resource for developing new materials, insect adhesives have been little studied so far. Here, we examined the adhesive properties of the larval glue of D. melanogaster. This glue is made of glycosylated proteins and allows the animal to adhere to a substrate...

Data from: Olive oil bioactives protect pigs against experimentally-induced chronic inflammation independently of alterations in gut microbiota

Martin Liehr, Alessandro Mereu, Jose Javier Pastor, Jose Carlos Quintela, Stefanie Staats, Gerald Rimbach & Ignacio Rodolfo Ipharraguerre
Subclinical chronic inflammation (SCI) is associated with impaired animal growth. Previous work has demonstrated that olive-derived plant bioactives exhibit anti-inflammatory properties that could possibly counteract the growth-depressing effects of SCI. To test this hypothesis and define the underlying mechanism, we conducted a 30-day study in which piglets fed an olive-oil bioactive extract (OBE) and their control counterparts (C+) were injected repeatedly during the last 10 days of the study with increasing doses of Escherichia coli...

Data from: Transcriptomic alterations during ageing reflect the shift from cancer to degenerative diseases in the elderly

Peer Aramillo Irizar, Sascha Schäuble, Daniela Esser, Marco Groth, Christiane Frahm, Steffen Priebe, Mario Baumgart, Nils Hartmann, Shiva Marthandan, Uwe Menzel, Jule Müller, Silvio Schmidt, Volker Ast, Amke Caliebe, Rainer König, Michael Krawczak, Michael Ristow, Stefan Schuster, Alessandro Cellerino, Stephan Diekmann, Christoph Englert, Peter Hemmerich, Jürgen Sühnel, Reinhard Guthke, Otto W. Witte … & Christoph Kaleta
Disease epidemiology during ageing shows a transition from cancer to degenerative chronic disorders as dominant contributors to mortality in the old. Nevertheless, it has remained unclear to what extent molecular signatures of ageing reflect this phenomenon. Here we report on the identification of a conserved transcriptomic signature of ageing based on gene expression data from four vertebrate species across four tissues. We find that ageing-associated transcriptomic changes follow trajectories similar to the transcriptional alterations observed...

Data from: Patterns of size variation in bees at a continental scale: does Bergmann’s rule apply?

Maxence Gérard, Maryse Vanderplanck, Markus Franzen, Michael Kuhlmann, Simon G. Potts, Pierre Rasmont, Oliver Schweiger & Denis Michez
Body size latitudinal clines have been widley explained by the Bergmann’s rule in homeothermic vertebrates. However, there is no general consensus in poikilotherms organisms in particular in insects that represent the large majority of wildlife. Among them, bees are a highly diverse pollinators group with high economic and ecological value. Nevertheless, no comprehensive studies of species assemblages at a phylogenetically larger scale have been carried out even if they could identify the traits and the...

Pietsch, Bo Yang, Peter Kühn, Thomas Scholten, Yuanyuan Huang, Chao Wang, Michael Staab, Katrin N. Leppert, Christian Wirth, Bernhard Schmid & Keping Ma
Forest ecosystems are an integral component of the global carbon cycle as they take up and release large amounts of C in short time (C flux) or accumulate it over longer time (C stock). However, there remains uncertainty about whether and in which direction C fluxes and in particular C stocks may differ between forests of high vs. low species richness. Based on a comprehensive dataset derived from field-based measurements, we tested the effect of...

Biodiversity citizen science: outcomes for the participating citizens

Maria Peter, Tim Diekötter, Tim Höffler & Kerstin Kremer
1. Citizen science (CS) is regarded a promising format in environmental and sustainability education as well as in science education. CS projects often assume that participation in the project influences, for example, participants' knowledge or behaviour. 2. We investigated whether and to what extent biodiversity citizen science (BDCS) projects, from the participants' self-reported perspective, achieve the following six participant outcomes: (1) content, process, and nature of science knowledge, (2) skills of science inquiry, (3) self-efficacy...

Higher phage virulence accelerates the evolution of host resistance

Carolin Wendling, Janina Lange, Heiko Liesegang, Michael Sieber, Anja Pöhlein, Boyke Bunk, Jelena Rajkov, Olivia Roth & Michael Brockhurst
Pathogens vary strikingly in their virulence and the selection they impose on their hosts. While the evolution of different virulence levels is well studied, the evolution of host resistance in response to different virulence levels is less understood and as of now mainly based on observations and theoretical predictions with few experimental tests. Increased virulence can increase selection for host resistance evolution if resistance costs are outweighed by the benefits of avoiding infection. To test...

Masden, Gary D. Clewley, Mindaugas Dagys, Olivier Duriez, Klaus‐Michael Exo, Wolfgang Fiedler, Andrea Flack, Guilad Friedemann, Johannes Fritz, Clara García-Ripollés, Stefan Garthe, Dimitri Giunchi, Atanas Grozdanov, Roi Harel … & Victoria Saravia
Wind turbines and power lines can cause bird mortality due to collision or electrocution. The biodiversity impacts of energy infrastructure (EI) can be minimised through effective landscape-scale planning and mitigation. The identification of high-vulnerability areas is urgently needed to assess potential cumulative impacts of EI while supporting the transition to zero-carbon energy. We collected GPS location data from 1,454 birds from 27 species susceptible to collision within Europe and North Africa and identified areas where...
